[PATCH 2/2] remoteproc: imx_dsp_rproc: Add support of coredump

[Shengjiu Wang]

Add call rproc_coredump_set_elf_info() to initialize the elf info for
coredump, otherwise coredump will report an error "ELF class is not set".

Remove the DSP IRAM and DRAM segment in coredump list, because after
stop, DSP power is disabled, the IRAM and DRAM can't be accessed.
